系统在设计时应使水泵在变频器和工频电网之间的切换过程尽可能快,以保证供水的连续性,水压波动尽可能小,从而提高供水质量。但元件动作过程太快,会有回流损坏变频器。为了防止故障的发生,硬件上必须设置闭锁保护,即1Q与4Q,2Q与5Q,3Q与6Q不能同时闭合。
2 系统软件设计
控制系统软件是指用梯形图语言编制的对3台泵进行控制的程序。它对3台泵的控制,主要解决系统的手动及自动切换、各元件和参数的初始化、信号及通讯数据的预处理、3台泵的启动、切换及停止的条件、顺序、过程等问题。
当变频器输出频率达到频率上限,供水压力未达到预设值时,发出加泵信号,投入下1台泵供水。当供水压力达到预设值,变频器输出频率降到频率下限时,发出减泵信号,切除在工频运行方式中的1台泵。系统刚启动时,情况简单,首先启动一号泵即可。但考虑3台泵联合运行时情况复杂,任1台或2台泵可能正在工频自动方式下运行,而其他泵则可能在变频器控制下运行,因此必须预先设定增减水泵的顺序。即获得加泵信号后,按照1号泵、2号泵、3号泵的顺序优先考虑。获得减泵信号后,按照3号泵、2号泵、1号泵的顺序优先考虑。
为了防止故障的发生,软件上也必须设置保护程序,保证1Q与4Q、2Q与5Q、3Q与6Q不能同时闭合。在加减泵时必须设置元件动作顺序及延时,防止误动作发生。
